Lower Mississippi Saltwater Intrusion Updates

As a result of the historic drought throughout the Mississippi River Valley, the rate of freshwater flowing down the Mississippi River has been dramatically low, allowing an intrusion of saltwater from the Gulf of Mexico to make its way upriver. Plaquemines Parish has already been affected by the intrusion, and other parishes are projected to be impacted over the next month including St. Bernard Parish, Jefferson Parish and Orleans Parish.
